I like Klairs a lot, I've tried creams before and I really liked it. I've decided to buy the serum to get rid of pigmentation, unfortunately, it's a really weak product, it's good for sensitive skin to make it stronger but it doesn't really work on pigmentation.

I really wanted to try Vitamin C serum cause everyone keeps raving about it but my sensitive skin dont like it.
I use only 2 drops mix with either klairs rich soothing serum or klairs lotion, everyday (recommended for sensitive skin). I feel that I got some pimples when using it or because of the klairs lotion. Either way, no improvement, doesnt strengthened my skin, although, it brightened my face a bit. The other downside is that, whenever I used it and when my hand sweat, by whatever reaction it is with the Vit C serum, it makes my hand smells like fried egg and I hate that.

I have been wanting to have this product and try it and when I finally did, it was okay. I have heard so many good things about it so I was very curious if it would work for me too. I had a vit c serum which was the ITS SKIN VC Effector but that didn't do much and wasn't very effective so I wanted to use another brand. I must say that this vit c serum gave me results. I wouldn't say that this product is the sole reason for the improvement but having this one in my routine made my acne scars and blemishes fade faster.

One thing I disliked about it though is that it oxidizes so fast. I only have this product for about 2 months and it has turned kind of yellowish. huhuhuhu I know oxidizes vit c won't be as effective anymore but I'm going to keep using it because it is so expensive!

As the title suggests, I'm not a fan of the oily texture. To me this feels more like a face oil than a serum, and if I review the product from that perspective, than it's not too bad, as it does what a face oil does - make your skin softer and help it retain moisture. But from a vitamin c serum perspective, it was just ok at best. There was some subtle brightening with long term use, but nothing that makes me go WOW. But my main gripe with this product was the oiliness and the shine it left my face, which as for something labeled as "a serum", is baffling. Things got better when I started mixing this with a moisturizer, but the results from this serum just weren't worth the efforts. Dry skin might actually like the facial oil characteristics of this serum though, but for my combo skin this just didn't quite work out.

I decided to try this because my face has a lot of different tones (my chin is darker, I have those blue dark circles that you notice in sunlight, my t-zone is red etc) and I want to give some boost to it. This is where the product is supposed to shine, because it's very versatile. I would love to say that this did something to my face, but it didn't improve it that much. It's also very drying, I've used the Mizon Hyaluronic Acid 100 before and it felt like heaven, it was sooooo moisturizing, yet didn't provide me any improvements. But this one doesn't do neither: it feels sticky and doesn't appear to do much. Maybe the results may come later, but I can say for sure that you won't see any immediate results (and I'm talking about after 2 weeks of use for example).
The thing is, it didn't break me out or did any bad things to my skin. It's a so-so product, to resume my experience.
